Perhaps these long sletider legs ma}^ be spread out on tlie surface of 

 the sand to imitate annelids and so serve as a lure for small fishes. 

 We had no opportunity to test this proposition. The very young 

 specimens did not show this distinction in the color of the legs, so 

 far as observed.

 total length of cheliped, 47™™; extent beyond the edge of the cara- 

 pace, 40'"™. 



When recently dried there are small smooth areas on the carapace 

 and legs, especiallj^ the last pair, that are lustrous and somewhat 

 iridescent; most of the under side of body and legs is smooth and 

 shining. 



At Bermuda it is a very common species. We found it abundant 

 in shallow water in April, 1898 and 1901, on the sandy bottoms of 

 sheltered coves and inlets, as near Walsingham Bay, Coney Island, 

 Hungry Bay, etc. 



It was also contained in the early collections of J. M. Jones, Dr. 

 F. V. Hamlin, G. B. Goode and others. Most of the more recent 

 collectors have also taken it, but all the specimens that I have seen 

 are small and probably immature, for none bear eggs. It was origi- 

 nally described by Dr. Stimpson from Charleston, S. C. and Beaufort, 

 N. C Its range extends from Cape Hatteras to the Antilles. Fort
